Strength and Muscle Related Outcomes for Nutrition and Lung Function in CF
Purpose
The goal of the study is to examine multiple markers of anthropometrics, body
composition, sarcopenia and frailty and compare them to dual energy X-ray absorptiometry
(DXA) output, which is considered the current clinical gold-standard tool to measure body
composition. The result of this study will provide detailed data regarding the nutrition
and body composition within this Cystic Fibrosis population and also provide a baseline
evaluation for use of these biomarkers in the future studies including evaluation of
nutritional intervention. Further, the study will also include psychosocial and other
patient-reported outcomes and medical contributors to understand their contributions to
the nutritional failure in the adult advanced lung disease population. Finally, the study
will evaluate both established and emerging nutritional and body composition parameters
and link them to clinical outcomes in adults with CF across the spectrum of pulmonary
function.

Arm Groups
| Arm | Description | Assigned Intervention |
|---|
|
Cohort 1
|
Forced expiratory volume in 1 second (FEV1) <60% predicted during the 12 months prior to
enrollment (>50% of measurements, eliminating periods of exacerbation). If no stable
spirometry data are available in the 12 months prior to enrollment, from the prior 24
months will be used.
|
-
Diagnostic Test: BMI and lean mass index from DXA
Estimate and compare correlation between lean mass index from DXA and BMI
-
Diagnostic Test: Anthropometric Measurements
Skinfold will be assessed with calipers. Circumference will be measured with a tape
measure.
-
Diagnostic Test: Hand-grip strength
A small, handheld dynamometer will be used to measure grip strength, a measure of
function, on each hand.
-
Diagnostic Test: Six-minute walk Test
This will be another functional assessment of fitness. Participants will be asked to walk
at their normal pace for 6 minutes.The total distance walked in that time will be
measured.
-
Diagnostic Test: Sit-to-Stand Test
This will be used as a functional assessment of fitness and lower extremity strength.
Participants will start seated on a chair and be asked to complete as many sit-to-stand
repetitions without using their arms for one minute.
-
Diagnostic Test: Short physical performance battery (SPPB)
This is an assessment of frailty. The test is completed in approximately 8 minutes. The
test consists of 3 assessments: 1) Balance tests where the participant stands and tries
to balance with their feet in various positions for 10 seconds each without assistance
(side-by-side, heel-to-side, and heel-to-toe); 2) Two 4-meter gait speed tests; and 3)
Chair-stand tests (single chair stand, 5 chair stands).
-
Diagnostic Test: BIA Sub-study
A minimum of 50 individuals will be enrolled. Body composition will be assessed at each
study visit using study bioelectrical impendence analysis (BIA).
-
Diagnostic Test: Accelerometry to assess physical activity
Participants will be provided with a wrist-worn accelerometer/heart rate monitor at the
baseline study visit and asked to wear it continuously for at least 3-10 days (two
weekdays, one weekend day). Approximately every 3 months, the participant will be asked
to again wear the accelerometer. Participants will be able to keep their accelerometers.
-
Other: Gastrointestinal (GI) and nutrition questionnaires:
Subjects will complete surveys regarding gastrointestinal (GI) symptoms, including the
Patient Assessment of Constipation (PAC-SYM) Score, Patient Assessment of
Gastrointestinal Symptoms (PACGI-SYM) Score, the Bristol Stool Chart, and the scored
Patient-Generated Subjective Global Assessment (PG-SGA).
-
Other: Psychosocial questionnaire: PHQ-8

-
Other: Psychosocial questionnaire: GAD-7
This is a 7-items scale that measures anxiety symptoms over the past two weeks, from not
at all to nearly every day.
-
Other: Psychosocial questionnaire: The Treatment Self-Regulation Questionnaire (TSRQ)
This is a 15-item scale that assesses the degree to which participants' motivation is
autonomous or self-regulated.
-
Other: Psychosocial questionnaire: CF Fatalism Scale
